YVILLIAM` ATKINSON, OF GRANBY, CANADA, ASSIGNOR OF ONE-HALF TO RICHARDJOHN RODDEN, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 455,603, dated July 7,1891. Application filed March 12, 1891. Serial No. 884,735. (No model.)

To all whom, t may concern:

Beit knownthat I, WILLIAM ATKINSON, carriage-maker, a citizen of Canada,residing at Granby, in the county of Sheiford, in the Province ofQuebec, Canada, have invented certain new and useful Improvements inVehicle- Springs; and I do hereby declare that the following is a full,clear, and exact description of the invention, such as will enableothers skilled in the artto which it appertains to make and use thesame.

My invention consists in certain improvements in the springs of thoseclasses of vehicles in which the springs are placed longitudinally withthe body of the vehicle; and

it is embodied in the device which is hereinafter described, and showninthe accompanying drawings, in Which- Figure l shows a side view of aspring possessing my improvements attached to the head-bar and rear aXleof a carriage. Fig. 2

shows in perspective the connection of the spring and the axle or thehead-bar, and Fig. 3 'shows the same-both in sectionV and elevation.Figs. 4. and 5 are separate views of parts hereinafter referred to byletter. Fig. 6 is a sectional view on line a; x. Fig. 7 shows the toptension-plate, and Fig. S the rub-plate. t

The spring-plates A are piled in the usual manner and in numberssuitable to the purpose'required. They are supported by the slide-platesB, which have secured to their ends by rivets, or otherwise, ifpreferred, the knuckle pieces D. These knuckle pieces have formed onthem the downwardly-proj ecting lugs E, which are pivoted to a block Fby the bolt G, which passes ythrough the block and through the lug E ateach of its ends. Projecting from the under side of the block F are twosteadying-pins H, which stand into the top side of the axle-bed I, orinto the head-bar, as the case may be, and hold the block in place. -Theblock F, axle-bed I, and axle J are all bound together by the screwedclip K, which lies in a groove formed in the sides and top of the blockF and passes down through the binder L, where it is secured by the nutsM. The yinner ends of the slideplates B are `forged round to form an eyeto receive the lower arm of the shackle \T.

.(Shown Yin Fig. 5.) The upper arm of thesel shackles passes througheyes formed in the ends of the top tension-plate O, which lies centrallyon top of the spring. The end portions of the plate O are sprung awayslightly from the spring-plates A, so that while the shackle N isstrained tightly between the slide-plates B and the top plate O, whichprevents all rattling, it is allowed to swing freely, so as to allow fortheir end play in the vertical action of the spring. A bolt P passesdown through the centers of the top tensionplate O, the spring-plates A,and the rub-plate Q and binds the whole firmly together'. This rub-plateQ is made, preferably, of spring-steel and has its end portions turneddownward and away from the bottom plate of the spring, so as to act as atension to the clips R, by which the cross-bars S, which connect thetw'o springs of the vehicle together, are secured to the springs. Therub-plate Q is considerably wider than the spring-plates, and this extrawidth being on the ou tside prevents the front carriage-wheel fromcoming in contact with the spring-plates an d wearing them when turningthe carriage. The outer legs of the clips R pass through both therub-plate` and the cross-bars S; but the inner leg passes only throughthe cross-bar. The cross-bars are thus held firmly in place. The smalllugs T are forged on the bottom spring-plate A, two on each side and ator near each end of the plate. Their ends are turned under theslideplates, so as to hold vthem securely in place and prevent thespring-plates rising from the slide-plates.

-Springs constructed as above described.

' hung low, make a light, easy-riding, and Wellequalized vehicle. l

What I claim as my invention, in the above described spring, is- A l.The combination, with the axles, of the slide-plates pivoted at theirouter ends thereto, the spring-plates seated upon the slideplates, thecentral tension-plate iiXed upon the spring-plates, and the linkspivoting the `ends of the tension-plate to the inner ends of theslide-plates, substantial-ly as described.

v2. In a vehicle-spring, the combination of IOO the slide-plates, theknuckles D, fixed to their outer ends and provided with the dependingperforated lugs, the blocks F, seated upon the axles between the lugs,the pivotal connections between the blocks and lugs, and the clips K,embracing the blocks and axles and serving to maintain them in fixedrelations.

3. In a carriage-spring, the top tensionplate O, secured to thespring-plates A by the Y central bolt P and clips R and having its endportions set up from Jthe spring-plates, so as to produce aspring-tension, and connected by shackles With the inner ends of theslide-plates B, substantially as herein shown and described.
